3 San Joaquin Valley Air Pollution Control District ii 3 April 17, 2006 f Reference No: C20060807 Rick Griffin San Joaquin County 00,720,0/7i Community Development Dept. 0,0 Z� ars 1810 East Hazelton venue n��YDot,% Subject: PA-0500726(SA)--Valley Organics, Inc.—920, 1060, 1 10 W. Frewert Road, Lathrop—APN 191- 260-22 & 191-270-04, 05 p , Dear Mr. Griffin: " The San Joaquin Valley Unified Air Pollution Control District (District) has.reviewed the project referenced above and offers the following comments: .j The entire San Joaquin Valley Air Basin is designated non-attainment for ozone and particulate matter (PM10 and PM2.5). This project would contribute to the overall decline in air quality due to construction activities in preparation of the site, and ongoing traffic and other operational emissions. Preliminary analysis indicates that this project alone would not generate significant air emissions. However, the increase in emissions from this project, and others like it, cumulatively reduce the air quality in the San Joaquin Valley. .A concerted effort should be made to reduce project-related emissions as outlined below:- Based on the information provided, it appears thal.this project will have a less-than-significant impact on the ambient air quality. However, the proposed project will be subject to the following District rules. The following items are rules that have been adopted by the District to reduce emissions throughout the San Joaquin Valley, and are required. This project may be subject to additional District Rules not enumerated below. To identify additional rules or regulations that apply to this project, or for further information, the applicant is strongly encouraged to contact the District's Small Business Assistance Office at (209) 557-6446. Current District rules i + can be found at http://www.valleyair.or./q rules/1 ruleslist.htm. C Hazardous Air Pollutants (HAPs)- This project may generate HAPs and a Health Risk Assessment (HRA) i may be required. Potential HAPs sources include project equipment, operations, and vehicles (the Air Resources Board (ARB) has designated diesel particulate emissions as a toxic air contaminant). On page 43 of the District's Guide for Assessing and Mitigating Air Quality Impacts, 2002 Revision (GAMAQI), the District addresses and defines sensitive receptors with respect to CEQA. +If the project is near sensitive receptors and HAPs are a concern, the project developer should perform a Health Risk Assessment(HRA). HRA guidelines promulgated by the California Office of Environmental Health Hazard Assessment (OEHHA) and OEHHA toxicity criteria must be used. The District recommends use of the latest version of the Hot Spots Analysis and Reporting Program (HARP) released by the Air Resources Board for a health risk assessment because it is the ' only software that is compliant with the OEHHA guidelines. An HRA should include a discussion of the toxic risk associated with the proposed project, including project equipment, operations, and vehicles. The GAMAQI defines the significance levels for toxic impacts as a cancer risk greater than 10 in a million and/or a hazard index (HI) of 1.0 or greater for chronic non-carcinogenic or acute risks. The project consultant should contact I the District to review the proposed modeling approach before modeling begins. For more information on hazardous air pollutants (HAPs) analyses, please contact Mr.,',Leland Villalvazo, Supervising Air Quality Specialist, at(559)230-6000 or hramodeler valle air.or . Rule 2010 (Permits Required) This rule requires any person constructing, altering, replacing or operating any source operation, which emits, may emit, or may reduce emissions to obtain an Authority to Construct or a Permit to Operate. is Northern Region Office Central Region Office Southern Region Office 4800 Enterprise Way 1990 East Gettysburg Avenue 2700 M Street,Suite 275 Modesto,CA 95356-8718 Fresno,CA 93726-0244 1!
